    Area of Science:

    • Radiology
    • Anatomy
    • Otorhinolaryngology

    Background:

    • Accurate interpretation of external carotid angiograms requires detailed knowledge of nasal fossa anatomy.
    • Lesions in or adjacent to the nasal cavity can alter normal vascular patterns.

    Purpose of the Study:

    • To describe the normal gross and angiographic vascular anatomy of the nasal fossa.
    • To illustrate the appearance of key arteries in various pathological conditions affecting the nasal cavity and nasopharynx.

    Main Methods:

    • Detailed description of normal gross anatomy of the nasal fossa.
    • Angiographic analysis of the vascular supply to the nasal fossa.
    • Illustration of arterial changes in common nasal and nasopharyngeal pathologies.

    Main Results:

    • The sphenopalatine artery and ethmoidal artery branches are crucial for nasal vascular supply.
    • Specific angiographic findings correlate with conditions like rhinitis, sinusitis, neoplasms, and vascular malformations.
    • Normal vascular anatomy provides a baseline for identifying pathological alterations.

    Conclusions:

    • A comprehensive understanding of nasal fossa vascular anatomy is essential for radiologists interpreting external carotid angiograms.
    • Angiography can effectively demonstrate changes in nasal vascularity associated with diverse pathologies.
    • This knowledge aids in the diagnosis and management of nasal and nasopharyngeal diseases.
